Description
B~CKGROUND OF THE INVI:NTION
The i.nvention relates generally to a novel manure spreader, more par-ticularly, is directed to a manure spreader includi.ng both a slow speed impeller and a high speed spinner positioned to receive a flow oE manure from the impeller and to spray the manure outwardly in a desired spray pattern.
Many types of spreaders have been developed by prior workers in the field which are usually employed in and about farms to utilize the fertilizer value of manure from herds of farm animals, for example, dairy cattle, in an efficient and economical manner~ The prior art manure spreaders have included flail type spreaders which are generally most commonly empl.oyed for use with solid manures. Other workers in the art have developed spray type spreaders which employ necessary tanks, hoses and accessory equipment to effectively di.stribute li~uid manures. Such wet type manures usually must first be processed to add sufficient water to pcrmit use with the spray equipment.
Both flail type spreaders and spray type spreaders ha~e been generally and widely utilized in the past and both types are ~uite common. However, certain operating difficulties and inefficiencies have arisen with the presently available spreading equipment due to the nature of the manures available for distribution. For example, spreaders designed for solid application, such as the flail type spreader, cannot readily be employed for use with liquid manures. Such types are particularly designed for use with solid manures and because of this, have limited storage capacity during periods

Both flail type spreaders and spray type spreaders ha~e been generally and widely utilized in the past and both types are ~uite common. However, certain operating difficulties and inefficiencies have arisen with the presently available spreading equipment due to the nature of the manures available for distribution. For example, spreaders designed for solid application, such as the flail type spreader, cannot readily be employed for use with liquid manures. Such types are particularly designed for use with solid manures and because of this, have limited storage capacity during periods
- 2 -6~3 of application. Also, because of -the load characteristics in-herent when spreading solid type manures, the prior art type of flail type spreader had to be ruggedly constructed and all parts had to be designed of increased strength to handle the solid materials. Despite the increased structural strength capabilities built into the equipment, there has been evidence of considerable wear and brea]cage, such as bearing wear, chain breakage and mechan-ical damage to the operating parts due to the nature of the solid manures.
In the case of prior art liquid type spreaders, the presently available prior art types incorporate a tank-like vehicle which is suitable only for use in the application of liquid manures.
Accordingly, such spray type spreaders were suitable for use only with waste materials that had previously been pretreated prior to introduction into the tank of the spreader vehicle in order to provide an effluent specifically designed for use with the specific spreader.
SU~ ~RY OF THE INVENTION
The present invention relates generally to a liquid and semi-liquid type manure spreader, and more particularly, is directed to a manure spreader incorporating a V-shaped body 116~46~
1 for holding the manure, an i.mpeller having a pl.urality of planar sides and blades positioned near the hottom of the body to direct the manure, an outlet gate in a side of the body and a high speed spinner receiving the effluent from the gate for spray distributi.on as the spreader is propelled.
The manure spreader of the present invention i.ncludes a whee]ed, open tank into the top of which liquid and/or semi-lic~uid manuLes can be easily Led by usi.ng existing, readil.y avai`labLe loading equipment. The body of the spreader is generally V-shaped in cross-sectiona]. configuration and incorporates neal- the bottom thereof a heavy duty, chopper-type auger- or ;.mpe~ler. The impeller includes an elongated body inc]udiny planar side.s and a E~l.ura]i.ty of separate hlades an~ularly outward~y projecting from the sides. The i.mpe].ler is ].on~itudinal.ly pos:itioned near the apex of the V-shap(? of the hody and has ;ts hlades positioned yenera:lly in the confi~urati.on of a he].ix, a rear port;.on of which helix ls designecl to propel manllre lrom the rear of the tank to a medial.ly positioned man~.lre exi.t gate and a front portion ot which heli.x is designed to propel. manure from the front of the body toward the medially positioned gate.
A high speed spinner is affi.xed in rotary engaclement exteriorly o~ the spreader body in position to receive the effluent from the gate and to direct the effluent in a spray pattern over the fi.eld to be so treated. Preferably the spinner rotates at a rotative speed that is from ten to fifteen times the rotational speed of the i.mpell.er wherehy both devices are rotated in unison, in opposite directions and at proportional rates of speed. A hinged deflector can be " 1~6^~4~`8 1 emp~.oyed in conjunction with the spinner in the path of the ef~luent from the spinner to vary the spray pattern to suit the existing fi.eld conditions.
In the preferred embodiment, the spinner is provided with a plurality of angularly offset buckets or scoops whereby only a portion of the buckets will. be in the same re~.ative angular contact with manure at any given instance. In this manner, the staggeri.ng of the scoop angular orientation results in a device that is capab]e of operation at greatly reduced horsepower requirements. The spinne.r scoops are preferahly forwardly curved to provide a better manure throwing pattern.
It is therefore an object of the present invention to provide an lmproved manure spreader of the type set forth.
It i.s another object of the present invention to provide a nove~ manure spreader which includes an open, V-shaped tank wi.th a longitucl.inally a]igned, doubl.e direction, planer sided impell.~r positioned near the bottom of the hody.
It is another ohject of the present invention to provide a novel manure spreader featuring an open tank with sides and separate blades suitable to move liquid and semi~ uid material from both the front of the tank and from the rear of the tank through the side outlet to a spinner for spreading purposes.
It is another object of the present i.nvention to provide a novel manure spreader including an open tank e~uipped with a scruare auger having a plurality of individual chopper type blades, some of the b~.ades being arranged in a forwardly directed helix and other of the blades being arranged in a rearwarcll.y directed helix, the tank having a side opening 1 i.ntermedi.ate its ends wherein the auger di.rects the manure to the side opening, a spinner positioned at the side opening exteriorly of the tank for sprayinq the manure and a drive mechanism arran~ed to rotate the spinner at many times the rotational speed of the auger.
It is another object of the present invention to provide a novel manure spreader i.nc]uding a generally V-shaped tank, a dual directi.onal impel]er longitudinall.y arranged interiorl.y o~ the tank, the impeller having a square body, a spinner rotative:l.y carried outside of the tank in position to receive the effluent from the impeller intermediate the ends of the tank and means to rotate the spinner at many times the rotative speed of the impeller.
It is another object of the present invention to provide a novel manure spreader compri.s.ing an open, gellerally V-shaped tank, an impeller featuring a square body .l.ongitudinally arran~ed for rotati.on near the bottom of the body for manure directiolla]. purposes, a spinner receivin-~ the effluent trom the impel..l.er and bei.ng rotatively positioned exteri.orly of the~body, a drive means r:otating the impeller and the spinner, the drive means inc].uding means to rotate the spinner at fr-om ten to fifteen times the rotational. speed of the impel.ler and means to vary the spray pattern of the effluent from the spinner.
It is another object of the present invention to provide a novel li~uid and semi.-liquid manure spreader that is simple in construction, rugged in design and troublefree when in operation.

1~6~8 1 DESCRIPTION OE TI~E PRE~RRED FMBODIMENTS OF T.~IE IMVENIION
Although specific terms are used in the following descriytion for the sake of c3arity, these terms are intended to refer on]y to the particular structure of the invention selecteci for illustration in the drawings, and are not intended to define or limit the scope of the invention.
Referriny now to the drawings, there is shown ir Figs.
1-3 a manure spreader generall.y ciesignated 10 which comprises essentially a wheeled, tank type body 12 having an open top 14 into which the manure (not shown) to spread can be readil.y dumpeci. The tank 12 is g~nerally V-shaped in configura~ion ancl is c.arried upon a sui.table, sturdy chassis 36 in a conventi.onal manner. Ihe chassis 36 ls arranged for easy transport over the field to be treated by empl.oying a p.lurality of right and left whee.ls 32, 34 mountecl .in pairs uF)on conventional axles 38 in we:ll knc)wn manner.
lhe mcln~ spreader J0 is conventionally transported and powered by a tractor or other farm eqll:ipmellt ~not shown) i.n well known manner. For exampl~.?, a hitch 42 i.s il.l.ustratecl in Fig. 1. for usual towing connection to the piece of farm equipment. Power for operation of the device is a~so conventionall.y drawn from the tractor or other farm equipment through a rotating drive shaft 44 wh:ich is supplied with a suitabl.e coupling 45 for connection to the tractor PTO (not shown) in usual manner.
As best seen in Figs. 2 and 3, an impeller 1.28 is lonyitudinally positioned within the interi.or of the body 12 near the bottom of the V-configuration. The impel]er 12 4~B
1 extends -the entire lenyth o~ the tan7c body 12 and forwardly has its shaft 130 coupled to the drive shaEt 4~ in known manner whereby rotation of the drive shaf-t 4~ by the trac-tor (not shown) will cause correspondillg rotation of the impeller 128.
The impe]ler shaft 130 is journalled within conventional forward and rearward bearinys 20 for rotation relative to the tank or body 12. The impeller shaft 130 ex-tends forwardly in a shaft extension 19 for powering the manure spreader system as hereinafter more fully set Eorth.
Referring now to Figs. 2 and 6, it will be observed that the auger or impeller 128 includes an elonga-ted body 132 ha~ting planar sides 136, 138, 140, 142 which are secured to the impeller shaft 130 in conventional, sturdy manner, such as by we~lding or other interconnection. A plurality of individual }?lanar blades 13~ are defined one ~rom ano-ther and are welded or otherwise secured to the impeller body 132 in the general conL:iguration of a helix for manure directing purposes. The helix is divided into a rearwardly directed helix 24 which acts to urge manure (not shown) contained within the tank 12 rearwardly within the body from the front wall 31 to the side outlet 48 and a longi.tudinally juxtaposed forwardly directed helix 26 which serves to urge the manure forwardly within the tank 12 from the rear wall 30 toward the side opening 48. The rearwardly directed helix 24 terminates rearwardly adjacent to the side opening 48. An unloading section 28 is defined at the interface between the rearward helix 24 and the forward helix 26 to efficiently direct the manure (not shown) through the side opening or gate 48. As illustrated, the forwardly directed helix 26 terminates forwardly adjacent to the side ~6~4~;8 1 opening 48 at the unloading secti.on 28. Accordin~ly, upon impeller rotation, the aual directed helices 24 and 26 tend to urge the liquid and semi-liquid manure contained within the tank 12, both frvm the front wall 31 and from the rear wall, 30 toward the unloading opening 48. ~s illustrated, the unloadin~
opening 48 is positioned c.]oser to the tank ~od.y front wall 31 and further from the tank body rear wall 30.
~ ne of the -~ank body incl.ined sidewal.ls 46 or 47 is provided with the side opening or gate 48 to permit the manure (not shown) contained within the tank body 12 and driven by the impeller 128 to exit therethrough for manure spreading purposes. The gate or opening 48 tranverse]y a]i.qns with the un:l.oading section 28, for si.cle un.loading to the spimner 154.
It is noteworthy that the unloading section 38 comprises the interface between the rearward:ly directing heli.x 24 and the for wardl,y ciirecting helix 26 whi.ch serves to urge or sweep the manure tr.ansverse].y through the openillq 48 as the impe:ller l2~
is rotated uE~on the application of rotative forces to the drive shaft 44.
Referring now to Fi.gs. 1 and 3, a spreader chamber 50 ls wel.ded or otherwise secured exteriorly to a tank sidewall 46 or 47 and comprises generally a right wal:l 52, a left wa]l 53 and an interconnecting floor or base wall 56. The manure spreading spinner 154 is mounted for rotation between the right and left spreader chamber walls 52, 53 and can have its shaft 160 journalled within respective front and rear bearings 62 in a conventional manner. As illustrated in Fig. 3, the spreader chamber floor 56 forms a continuation of the spreader body inclined wall 47 so that the manure delivered to the opening 48 ;8 1 through the interaction of the rearwardly directed helix 24, the forwardly directed helix 26 and the unloading section 28 dumps or flow~ the manure directly from within the tank 12 into the spreader chamber 50 for throwing or spreading by the spinner 154 as the spinner is rotated at high rotative speeds.
If des.ired, a door, (not shown) can be provided in known manner to close the opening 48 in the body wall 46 when the device 1.0 is not in use and to expose the opening 48 when i.t is desired to employ the spreader 10 for manure spreading purposes.
As above set forth, the spinner shaft 160 is journall.ed between the right and left bearings 62 and is positioned to receive and to prope] the manure (not illustrated) which i.s driven into the spreader chamber 50 upon rotation of the impeller 120. It is a feature of this invention to rotate the spinner 154 many times faster than the speed of rotation of the auger or impeller 128. By dri.ving the auger at a relative].y sl.ow rate of speed, the manure loaded within the i.nterior of the tank 12 can be most advantageously directed to the opening or gate 4~ without the stranding of sol.ids upon the inclined body sidewalls 46, 47. The hi.gh speed rotati.on of the spinner ].56 provi.des maximum efficiency in spreading or throwing the manure. Additi.onally, the construction comprising the opening or gate 48 combined with the slow speed of rotation of the impeller or auger l2R
facilitates the handl.ing of drier materials without stranding of the solids within the body prior to spilling into the spreader chamber 50.
Due to this capability of handling a full range of materials from very wet to very dry, the manure spreader 10 of 1 the present invention can be employed to handle a wider variety of materials to be spread in a troublefree and hi~hly efficient manner. The individual auger blades 134 are preferably formed of planar steel sheet of sufficient thickness for the operation to provide adequate strength. The blades 134 extend in width the entire width of thei.r associated auger sides 136, 138, 140, 142 and, as best seen schematically in Fig. 7, are positioned in dual, opposite helical arrangement. Additionally, as illustrated, the blades 134 are endwardly curved and extend near the bottom of the tank upon rotation for a better and more eEfici.ent manu~e movement forwardly ard rearwardly through t:he tank 12.
Referring now to Fig. 1, one èmbodiment of a spinner drive mechanism will now be described. ~s illustrated, the ~-luger shaft 130 extends through the front bearing 20 in a conventional shaft extension 19 to which is pinned or otherwise secured a first ~e.ar drive system 82. Accordingly, when the drive shaft 44 is connected to the tractor PTO (not shown) through the coupling 45, rotation of the drive shaEt 4~ causes simultaneous rotation of the impeller shaft 130 and the shaft extension 19. ~s above set forth, it is preferably to rotate the impeller shaft 130 at a relatively slow speed and the spinner shaft 156 at a relatively high speed. The power sprocket 84 drives a driven sprocket 86 thr.ough a conventional drive chain 98. The driven sprocket 86 in turn powers the second gear drive system 88 to thereby cause higher speed rotation of the shaft 156 through the coupling 90.
The drive system described is illustrative only, and it is contemplated that other gear systems or other mechanical . . ,;
..~
4~iB
1 drives can be employed to -transmit ro-tative power Erom the tractor PTO (not illustrated) to rotate simu:Ltaneousiy the auger 12~ and the spinner 154. See Lor example the gear drive train illustrated in my co-pend:ing Canadian patent application, Serial No. 374,224 filed March 30, 1981.
Preferably, the auger or impeller 128 is rotated by -Lhe drive shaf-t 44 at a rotative speed of approximately fifty revolutions per minute. Simultaneously, through the first and second gear drive systems 82, 88, above enumerated, the spinner 154 is optimumly rotated at a speed of from approximately five hundred and forty revolutions per minute -to seven hundrea and fifty revolutions per minute to provide an optimum spray ~attern.
~ s i:Llustr~ted in Figs. 1, 2 and 3, in order to easily va~y the spreader pattern, the spreader chamber 50 may be L~ovided with an overhead deflector 70 which can be arranged for vertical or llinged adjustment relative to the spreader 154 jl? we~l known manner. In the embodiment illustrated, a hydraulic cylinder 72 is supported in pivotal manner from the ~O body 12 through a stationary bracket 80 .in a manner to reciprocally move the deflector 70 relative to the spinner 154. As best seen in Fig. 3, the cylinder 72 func-tions its piston rod 74 in the direction indicated by the arrow 76 to move the deflector 70 between the positions illustrated in full lines and phanton lines. In one embodiment, as illustrated, the deflector 70 may be provided with suitable guides 78 to facilitate the inclined, vertical movement indicated. If desired, the cylinder 72, the piston arm 74 and the deflector 70 could also be arranged to pivot the deflector relative to ... .
~1468 1 the spinner 1.54. As above set forth, the purpose of the deflector 70 is to vary the spray pattern, and this variation may be accomplished in any sui.table, efficient manner.
As best seen in Fig. 3 the shaft 130 of the auger 128 rotatively carries an enclosing, elongated, rectangular or square cross section body 1.32 which can be secured to the impeller shaft 128 in conventiona], sturdy manner, such as wel.di.ng or other suitab].e strong, known type of i.nterconnection. A plurality oL- individual b].ades ]34 are welded or otherwise secured to the straight si.des ].36, 138, 1.40 and 1.42 which define the impeller hody 1.32. The b~ades 134 are arranged about the body 132 in the conf3.9urati.on of helices 24, 26 to direct or push the manure (not shown) through the body 12 to the ~ate or opening 48 and thence to the spinner 1.54 for spreading purposes. ~s i.ll.ustrated, each blade 134 preferably extends i.n l.enyth the enti.re thickness or wi.dth of i.ts correspondi.ng side 136, 138, 140 or 1.42. Each blade 134 :is generally reCtatlgU]ar in configurati.on and terminates outwardl.y i.n a rounded edge 44 to efficiently confor~l to the bottom configuration of the spreader tank 12. The rounded edges provi.de an efficient shape for positive cleanout as the shaft is rotated. Preferabl.y, the blades 134 tilt rearwardly at an angle of approximately five degrees to ten degrees from the normal to the axis of the shaft 128 to reduce friction and torque l.oad. See Fig. 6. Additionally, the five to ten degree angularity of the klades aids in moving dry material.s through the body by slowing down the progress of such materials.
The square corners 146, 148, 150, 152 defined by the straight, angularly interconnected body sides, 136, ]38, 140 11~;1468 1 142 create a pulsati.ng or agitatlng action in the manure (not illustrated) when the shaft 130 is rotated to aid in breaking up large particles al~d in directing the manure toward the spinner 154. Add:itionally, the agitation of the manure caused by ~he repeated impacts of the impeller body corners 146, 148, 150, 152 together with the chopping action of the individual blades acts to discourage the manure from bridging over the impeller 128 to prevent interference with the movement of the manure within the body 12 toward the spinner 1.54. The cu-tting 1~ action of the individual blades 134 combines with the pulsating action created by the rotation of the body corners 146, 148, .l50, 152 to pulsate or vibrate the material. The combined actions of the blades 134 and the body 132 as the shaft is rot,ated aids in transportatian of the manure through the body and thus accommodates a great variety of materials from substantially semi-solid to substantially liquid compositions.
Referring now to Figs. 4 and 5, one embod1.ment of a spinner 154 is illustrated comprising generally a shaft 156 which is suitabl.y journalled within bearings 62 which are 2~ mounted within the spreader chamber walls 52, 53 for high speed rotation within a spreader chamber 50. Inasmuch as it is ' contemplated that a suitable gear train drive to rotate the spinner 154 can be developed in known manner similar to the drive previously shown and described in Fig. 1, the drive need not be further described at this time. Suffice it to say that it is desirable to rotate the spinner 154 at a considerably greater speed than the impeller, 128, and any suitable known type of drive that will accomplish this resul-t that could be efficiently employed would be satisfactory for the purpose.
1 The spreacler or spinner l.54 comprises a plurality of indiv:i.d~al, an~ular scoops or huckets .158 each of w~ich is defined by a radially oriented roof 160, a radially oriented floor, 162, a left slde ~64 and a riqht side 166. Preferably, the respective roofs 160 and floors 1.62 of the individual scoops 158 are curved in the di.rection of rotati.on to ai.d in the manure throwi.ncJ or spreading function. As il]ustrated, each scoop or bucket 158 de.ines an arc of ninety degrees whereby four angular1y conti.g~lous scoop~ 158 can be positi.oned about the spinner shaft 156. In a preferred emodi.ment, as best seen i.n Fig. 5, a p.lur.li.ty of four sep~rators ~.fi8, 17n " 72, 174 are employed to define four contiquous, ci.rcularl.y arrangecl 5COOpS 158. As il:lust^ated, each of the separators 1.68, 170, .L72, 174 serves both as the roof 1.60 of one sct)op and as the floor lfi2 of the next circularly adjacent scoop.
Referling sti:l.l to Fi.gs~ 4 and 5, it wil..l. be seen that the spinner ].54 comprises a p~urality oi thlee juxt.aposecl scoop sections ].76, l.78, 180 each of which i.ncludes a plura] i.ty of four circulal:ly adjacent scoops or buckets 158. It is noteworthy that the scoops .1.58 of the scoop section 176 are circularly angul.arly offset from the scoops 15~ of the scoop section 17~ by an angle of thirty degrees. Simi].ar:l.y, the scoops 1.58 of the scoop section ].80 are circularly angularly offset from the scoops 158 of the scoop section 178 by an ang]e of thirty degrees to therehy provide a balanced design and to prevent undue vibration upon high speed rotation of the spinner. The staggered arrangement of the scoops 158 i.n the various scoop sections surprisingl.y results in consi.derably reduced horsepower requirements necessary to rotatively drive -~6 1 the splnner 154 during the manure spreading operations. The curvilinear design of the individual scoops cr buckets 358 coupled with the high speed rotation of the spinner acts to trap a cushion of air about the shaft 156 whereby the material to be spread rides centrifica31y outwardly in the scoops, a phenomenon that also appears to reduce the ~uantity of energy required to rotate the spreader 154.
As best seen in Fig. 4, a sturdy, steel, replaceab3e chopping strip 182 is removably affixed at the respective ends of the separators 168, 170, 172, 174 to aid in chopp;ng solid manure particles as the manure is urged toward the spinner l54 by the rotative action of the impeller 128. Preferab]y, teeth 184 are formed ln the chopping strip edge to enhance the chopping action while the spinner is rotated at high speed.
Due to the considerable wear occasioned by repeated impacts of the chopping strips 182 against the manure, the chopping strips are preferably removab3y connected by bolts 186 which position through aligned openings in the respective chopping strips 182 and the separators 168, 170, 172 and 174. Additiona]ly, to increase the usetul ]ife of a chopping strip 182, a second row of teeth 188 preferably can be formed at the second longitudinal edge. ~ccording3y, when the first row of teeth 184 in a chopping strip demonstrate sufficient wear, then the second row of teeth 188 can be readily brought into use by simply removing the connection bolts 186, reversing the chopping strip and then reconnecting with the second row of teeth positioned radially outwardly.
A]though the invention has been described with a certain degree of particularity, it is understood that the 1 present di.sclosllre has been made only hy ~ay of example and that numerous changes in the details of construction and the combinati.on and arrancJement of parts may be resorted to without departiny .Erom the spiri-t and scope of the inven-tion.

In the case of prior art liquid type spreaders, the presently available prior art types incorporate a tank-like vehicle which is suitable only for use in the application of liquid manures.
Accordingly, such spray type spreaders were suitable for use only with waste materials that had previously been pretreated prior to introduction into the tank of the spreader vehicle in order to provide an effluent specifically designed for use with the specific spreader.
SU~ ~RY OF THE INVENTION
The present invention relates generally to a liquid and semi-liquid type manure spreader, and more particularly, is directed to a manure spreader incorporating a V-shaped body 116~46~
1 for holding the manure, an i.mpeller having a pl.urality of planar sides and blades positioned near the hottom of the body to direct the manure, an outlet gate in a side of the body and a high speed spinner receiving the effluent from the gate for spray distributi.on as the spreader is propelled.
The manure spreader of the present invention i.ncludes a whee]ed, open tank into the top of which liquid and/or semi-lic~uid manuLes can be easily Led by usi.ng existing, readil.y avai`labLe loading equipment. The body of the spreader is generally V-shaped in cross-sectiona]. configuration and incorporates neal- the bottom thereof a heavy duty, chopper-type auger- or ;.mpe~ler. The impeller includes an elongated body inc]udiny planar side.s and a E~l.ura]i.ty of separate hlades an~ularly outward~y projecting from the sides. The i.mpe].ler is ].on~itudinal.ly pos:itioned near the apex of the V-shap(? of the hody and has ;ts hlades positioned yenera:lly in the confi~urati.on of a he].ix, a rear port;.on of which helix ls designecl to propel manllre lrom the rear of the tank to a medial.ly positioned man~.lre exi.t gate and a front portion ot which heli.x is designed to propel. manure from the front of the body toward the medially positioned gate.
A high speed spinner is affi.xed in rotary engaclement exteriorly o~ the spreader body in position to receive the effluent from the gate and to direct the effluent in a spray pattern over the fi.eld to be so treated. Preferably the spinner rotates at a rotative speed that is from ten to fifteen times the rotational speed of the i.mpell.er wherehy both devices are rotated in unison, in opposite directions and at proportional rates of speed. A hinged deflector can be " 1~6^~4~`8 1 emp~.oyed in conjunction with the spinner in the path of the ef~luent from the spinner to vary the spray pattern to suit the existing fi.eld conditions.
In the preferred embodiment, the spinner is provided with a plurality of angularly offset buckets or scoops whereby only a portion of the buckets will. be in the same re~.ative angular contact with manure at any given instance. In this manner, the staggeri.ng of the scoop angular orientation results in a device that is capab]e of operation at greatly reduced horsepower requirements. The spinne.r scoops are preferahly forwardly curved to provide a better manure throwing pattern.
It is therefore an object of the present invention to provide an lmproved manure spreader of the type set forth.

1~6~8 1 DESCRIPTION OE TI~E PRE~RRED FMBODIMENTS OF T.~IE IMVENIION
Although specific terms are used in the following descriytion for the sake of c3arity, these terms are intended to refer on]y to the particular structure of the invention selecteci for illustration in the drawings, and are not intended to define or limit the scope of the invention.
Referriny now to the drawings, there is shown ir Figs.
1-3 a manure spreader generall.y ciesignated 10 which comprises essentially a wheeled, tank type body 12 having an open top 14 into which the manure (not shown) to spread can be readil.y dumpeci. The tank 12 is g~nerally V-shaped in configura~ion ancl is c.arried upon a sui.table, sturdy chassis 36 in a conventi.onal manner. Ihe chassis 36 ls arranged for easy transport over the field to be treated by empl.oying a p.lurality of right and left whee.ls 32, 34 mountecl .in pairs uF)on conventional axles 38 in we:ll knc)wn manner.
lhe mcln~ spreader J0 is conventionally transported and powered by a tractor or other farm eqll:ipmellt ~not shown) i.n well known manner. For exampl~.?, a hitch 42 i.s il.l.ustratecl in Fig. 1. for usual towing connection to the piece of farm equipment. Power for operation of the device is a~so conventionall.y drawn from the tractor or other farm equipment through a rotating drive shaft 44 wh:ich is supplied with a suitabl.e coupling 45 for connection to the tractor PTO (not shown) in usual manner.
As best seen in Figs. 2 and 3, an impeller 1.28 is lonyitudinally positioned within the interi.or of the body 12 near the bottom of the V-configuration. The impel]er 12 4~B
1 extends -the entire lenyth o~ the tan7c body 12 and forwardly has its shaft 130 coupled to the drive shaEt 4~ in known manner whereby rotation of the drive shaf-t 4~ by the trac-tor (not shown) will cause correspondillg rotation of the impeller 128.
The impe]ler shaft 130 is journalled within conventional forward and rearward bearinys 20 for rotation relative to the tank or body 12. The impeller shaft 130 ex-tends forwardly in a shaft extension 19 for powering the manure spreader system as hereinafter more fully set Eorth.
Referring now to Figs. 2 and 6, it will be observed that the auger or impeller 128 includes an elonga-ted body 132 ha~ting planar sides 136, 138, 140, 142 which are secured to the impeller shaft 130 in conventional, sturdy manner, such as by we~lding or other interconnection. A plurality of individual }?lanar blades 13~ are defined one ~rom ano-ther and are welded or otherwise secured to the impeller body 132 in the general conL:iguration of a helix for manure directing purposes. The helix is divided into a rearwardly directed helix 24 which acts to urge manure (not shown) contained within the tank 12 rearwardly within the body from the front wall 31 to the side outlet 48 and a longi.tudinally juxtaposed forwardly directed helix 26 which serves to urge the manure forwardly within the tank 12 from the rear wall 30 toward the side opening 48. The rearwardly directed helix 24 terminates rearwardly adjacent to the side opening 48. An unloading section 28 is defined at the interface between the rearward helix 24 and the forward helix 26 to efficiently direct the manure (not shown) through the side opening or gate 48. As illustrated, the forwardly directed helix 26 terminates forwardly adjacent to the side ~6~4~;8 1 opening 48 at the unloading secti.on 28. Accordin~ly, upon impeller rotation, the aual directed helices 24 and 26 tend to urge the liquid and semi-liquid manure contained within the tank 12, both frvm the front wall 31 and from the rear wall, 30 toward the unloading opening 48. ~s illustrated, the unloadin~
opening 48 is positioned c.]oser to the tank ~od.y front wall 31 and further from the tank body rear wall 30.
~ ne of the -~ank body incl.ined sidewal.ls 46 or 47 is provided with the side opening or gate 48 to permit the manure (not shown) contained within the tank body 12 and driven by the impeller 128 to exit therethrough for manure spreading purposes. The gate or opening 48 tranverse]y a]i.qns with the un:l.oading section 28, for si.cle un.loading to the spimner 154.
It is noteworthy that the unloading section 38 comprises the interface between the rearward:ly directing heli.x 24 and the for wardl,y ciirecting helix 26 whi.ch serves to urge or sweep the manure tr.ansverse].y through the openillq 48 as the impe:ller l2~
is rotated uE~on the application of rotative forces to the drive shaft 44.
Referring now to Fi.gs. 1 and 3, a spreader chamber 50 ls wel.ded or otherwise secured exteriorly to a tank sidewall 46 or 47 and comprises generally a right wal:l 52, a left wa]l 53 and an interconnecting floor or base wall 56. The manure spreading spinner 154 is mounted for rotation between the right and left spreader chamber walls 52, 53 and can have its shaft 160 journalled within respective front and rear bearings 62 in a conventional manner. As illustrated in Fig. 3, the spreader chamber floor 56 forms a continuation of the spreader body inclined wall 47 so that the manure delivered to the opening 48 ;8 1 through the interaction of the rearwardly directed helix 24, the forwardly directed helix 26 and the unloading section 28 dumps or flow~ the manure directly from within the tank 12 into the spreader chamber 50 for throwing or spreading by the spinner 154 as the spinner is rotated at high rotative speeds.
If des.ired, a door, (not shown) can be provided in known manner to close the opening 48 in the body wall 46 when the device 1.0 is not in use and to expose the opening 48 when i.t is desired to employ the spreader 10 for manure spreading purposes.
As above set forth, the spinner shaft 160 is journall.ed between the right and left bearings 62 and is positioned to receive and to prope] the manure (not illustrated) which i.s driven into the spreader chamber 50 upon rotation of the impeller 120. It is a feature of this invention to rotate the spinner 154 many times faster than the speed of rotation of the auger or impeller 128. By dri.ving the auger at a relative].y sl.ow rate of speed, the manure loaded within the i.nterior of the tank 12 can be most advantageously directed to the opening or gate 4~ without the stranding of sol.ids upon the inclined body sidewalls 46, 47. The hi.gh speed rotati.on of the spinner ].56 provi.des maximum efficiency in spreading or throwing the manure. Additi.onally, the construction comprising the opening or gate 48 combined with the slow speed of rotation of the impeller or auger l2R
facilitates the handl.ing of drier materials without stranding of the solids within the body prior to spilling into the spreader chamber 50.
Due to this capability of handling a full range of materials from very wet to very dry, the manure spreader 10 of 1 the present invention can be employed to handle a wider variety of materials to be spread in a troublefree and hi~hly efficient manner. The individual auger blades 134 are preferably formed of planar steel sheet of sufficient thickness for the operation to provide adequate strength. The blades 134 extend in width the entire width of thei.r associated auger sides 136, 138, 140, 142 and, as best seen schematically in Fig. 7, are positioned in dual, opposite helical arrangement. Additionally, as illustrated, the blades 134 are endwardly curved and extend near the bottom of the tank upon rotation for a better and more eEfici.ent manu~e movement forwardly ard rearwardly through t:he tank 12.
Referring now to Fig. 1, one èmbodiment of a spinner drive mechanism will now be described. ~s illustrated, the ~-luger shaft 130 extends through the front bearing 20 in a conventional shaft extension 19 to which is pinned or otherwise secured a first ~e.ar drive system 82. Accordingly, when the drive shaft 44 is connected to the tractor PTO (not shown) through the coupling 45, rotation of the drive shaEt 4~ causes simultaneous rotation of the impeller shaft 130 and the shaft extension 19. ~s above set forth, it is preferably to rotate the impeller shaft 130 at a relatively slow speed and the spinner shaft 156 at a relatively high speed. The power sprocket 84 drives a driven sprocket 86 thr.ough a conventional drive chain 98. The driven sprocket 86 in turn powers the second gear drive system 88 to thereby cause higher speed rotation of the shaft 156 through the coupling 90.
The drive system described is illustrative only, and it is contemplated that other gear systems or other mechanical . . ,;
..~
4~iB
1 drives can be employed to -transmit ro-tative power Erom the tractor PTO (not illustrated) to rotate simu:Ltaneousiy the auger 12~ and the spinner 154. See Lor example the gear drive train illustrated in my co-pend:ing Canadian patent application, Serial No. 374,224 filed March 30, 1981.
Preferably, the auger or impeller 128 is rotated by -Lhe drive shaf-t 44 at a rotative speed of approximately fifty revolutions per minute. Simultaneously, through the first and second gear drive systems 82, 88, above enumerated, the spinner 154 is optimumly rotated at a speed of from approximately five hundred and forty revolutions per minute -to seven hundrea and fifty revolutions per minute to provide an optimum spray ~attern.
~ s i:Llustr~ted in Figs. 1, 2 and 3, in order to easily va~y the spreader pattern, the spreader chamber 50 may be L~ovided with an overhead deflector 70 which can be arranged for vertical or llinged adjustment relative to the spreader 154 jl? we~l known manner. In the embodiment illustrated, a hydraulic cylinder 72 is supported in pivotal manner from the ~O body 12 through a stationary bracket 80 .in a manner to reciprocally move the deflector 70 relative to the spinner 154. As best seen in Fig. 3, the cylinder 72 func-tions its piston rod 74 in the direction indicated by the arrow 76 to move the deflector 70 between the positions illustrated in full lines and phanton lines. In one embodiment, as illustrated, the deflector 70 may be provided with suitable guides 78 to facilitate the inclined, vertical movement indicated. If desired, the cylinder 72, the piston arm 74 and the deflector 70 could also be arranged to pivot the deflector relative to ... .
~1468 1 the spinner 1.54. As above set forth, the purpose of the deflector 70 is to vary the spray pattern, and this variation may be accomplished in any sui.table, efficient manner.
As best seen in Fig. 3 the shaft 130 of the auger 128 rotatively carries an enclosing, elongated, rectangular or square cross section body 1.32 which can be secured to the impeller shaft 128 in conventiona], sturdy manner, such as wel.di.ng or other suitab].e strong, known type of i.nterconnection. A plurality oL- individual b].ades ]34 are welded or otherwise secured to the straight si.des ].36, 138, 1.40 and 1.42 which define the impeller hody 1.32. The b~ades 134 are arranged about the body 132 in the conf3.9urati.on of helices 24, 26 to direct or push the manure (not shown) through the body 12 to the ~ate or opening 48 and thence to the spinner 1.54 for spreading purposes. ~s i.ll.ustrated, each blade 134 preferably extends i.n l.enyth the enti.re thickness or wi.dth of i.ts correspondi.ng side 136, 138, 140 or 1.42. Each blade 134 :is generally reCtatlgU]ar in configurati.on and terminates outwardl.y i.n a rounded edge 44 to efficiently confor~l to the bottom configuration of the spreader tank 12. The rounded edges provi.de an efficient shape for positive cleanout as the shaft is rotated. Preferabl.y, the blades 134 tilt rearwardly at an angle of approximately five degrees to ten degrees from the normal to the axis of the shaft 128 to reduce friction and torque l.oad. See Fig. 6. Additionally, the five to ten degree angularity of the klades aids in moving dry material.s through the body by slowing down the progress of such materials.
The square corners 146, 148, 150, 152 defined by the straight, angularly interconnected body sides, 136, ]38, 140 11~;1468 1 142 create a pulsati.ng or agitatlng action in the manure (not illustrated) when the shaft 130 is rotated to aid in breaking up large particles al~d in directing the manure toward the spinner 154. Add:itionally, the agitation of the manure caused by ~he repeated impacts of the impeller body corners 146, 148, 150, 152 together with the chopping action of the individual blades acts to discourage the manure from bridging over the impeller 128 to prevent interference with the movement of the manure within the body 12 toward the spinner 1.54. The cu-tting 1~ action of the individual blades 134 combines with the pulsating action created by the rotation of the body corners 146, 148, .l50, 152 to pulsate or vibrate the material. The combined actions of the blades 134 and the body 132 as the shaft is rot,ated aids in transportatian of the manure through the body and thus accommodates a great variety of materials from substantially semi-solid to substantially liquid compositions.
Referring now to Figs. 4 and 5, one embod1.ment of a spinner 154 is illustrated comprising generally a shaft 156 which is suitabl.y journalled within bearings 62 which are 2~ mounted within the spreader chamber walls 52, 53 for high speed rotation within a spreader chamber 50. Inasmuch as it is ' contemplated that a suitable gear train drive to rotate the spinner 154 can be developed in known manner similar to the drive previously shown and described in Fig. 1, the drive need not be further described at this time. Suffice it to say that it is desirable to rotate the spinner 154 at a considerably greater speed than the impeller, 128, and any suitable known type of drive that will accomplish this resul-t that could be efficiently employed would be satisfactory for the purpose.
1 The spreacler or spinner l.54 comprises a plurality of indiv:i.d~al, an~ular scoops or huckets .158 each of w~ich is defined by a radially oriented roof 160, a radially oriented floor, 162, a left slde ~64 and a riqht side 166. Preferably, the respective roofs 160 and floors 1.62 of the individual scoops 158 are curved in the di.rection of rotati.on to ai.d in the manure throwi.ncJ or spreading function. As il]ustrated, each scoop or bucket 158 de.ines an arc of ninety degrees whereby four angular1y conti.g~lous scoop~ 158 can be positi.oned about the spinner shaft 156. In a preferred emodi.ment, as best seen i.n Fig. 5, a p.lur.li.ty of four sep~rators ~.fi8, 17n " 72, 174 are employed to define four contiquous, ci.rcularl.y arrangecl 5COOpS 158. As il:lust^ated, each of the separators 1.68, 170, .L72, 174 serves both as the roof 1.60 of one sct)op and as the floor lfi2 of the next circularly adjacent scoop.
Referling sti:l.l to Fi.gs~ 4 and 5, it wil..l. be seen that the spinner ].54 comprises a p~urality oi thlee juxt.aposecl scoop sections ].76, l.78, 180 each of which i.ncludes a plura] i.ty of four circulal:ly adjacent scoops or buckets 158. It is noteworthy that the scoops .1.58 of the scoop section 176 are circularly angul.arly offset from the scoops 15~ of the scoop section 17~ by an angle of thirty degrees. Simi].ar:l.y, the scoops 1.58 of the scoop section ].80 are circularly angularly offset from the scoops 158 of the scoop section 178 by an ang]e of thirty degrees to therehy provide a balanced design and to prevent undue vibration upon high speed rotation of the spinner. The staggered arrangement of the scoops 158 i.n the various scoop sections surprisingl.y results in consi.derably reduced horsepower requirements necessary to rotatively drive -~6 1 the splnner 154 during the manure spreading operations. The curvilinear design of the individual scoops cr buckets 358 coupled with the high speed rotation of the spinner acts to trap a cushion of air about the shaft 156 whereby the material to be spread rides centrifica31y outwardly in the scoops, a phenomenon that also appears to reduce the ~uantity of energy required to rotate the spreader 154.
As best seen in Fig. 4, a sturdy, steel, replaceab3e chopping strip 182 is removably affixed at the respective ends of the separators 168, 170, 172, 174 to aid in chopp;ng solid manure particles as the manure is urged toward the spinner l54 by the rotative action of the impeller 128. Preferab]y, teeth 184 are formed ln the chopping strip edge to enhance the chopping action while the spinner is rotated at high speed.
Due to the considerable wear occasioned by repeated impacts of the chopping strips 182 against the manure, the chopping strips are preferably removab3y connected by bolts 186 which position through aligned openings in the respective chopping strips 182 and the separators 168, 170, 172 and 174. Additiona]ly, to increase the usetul ]ife of a chopping strip 182, a second row of teeth 188 preferably can be formed at the second longitudinal edge. ~ccording3y, when the first row of teeth 184 in a chopping strip demonstrate sufficient wear, then the second row of teeth 188 can be readily brought into use by simply removing the connection bolts 186, reversing the chopping strip and then reconnecting with the second row of teeth positioned radially outwardly.
A]though the invention has been described with a certain degree of particularity, it is understood that the 1 present di.sclosllre has been made only hy ~ay of example and that numerous changes in the details of construction and the combinati.on and arrancJement of parts may be resorted to without departiny .Erom the spiri-t and scope of the inven-tion.
